Statistička analiza obrade podataka u nekim seizmičkim refrakcijskim metodama: Primjer sintetičkih podataka

Abstract

The delay time method has gained attention in shallow seismic refraction survey because it has the capability to map the lateral thickness of overburden and relief of bedrock. This study addresses the comparison between the performances of the plus-minus and conventional reciprocal methods using a synthetic data. The interpretations obtained from both methods are reasonably comparable to the actual geophysical models. This suggests that either of the methods can be used to construct a geologic section. However, the result of randomized complete block design (RCBD) experiment shows a significant difference in the type of method used and this necessitate the need for further test. The pairwise comparison suggests that the plus-minus method produces a model that better mimics the actual data than the conventional reciprocal method.Metoda vremenskog kašnjenja često se koristi u istraživanju plitke seizmičke refrakcije jer ima mogućnost kartiranja lateralne debljine nadsloja i reljefa stijena. Ovaj rad bavi se usporedbom svojstava plus-minus i konvencionalnih recipročnih metoda korištenjem sintetičkih podataka. Interpretacije dobivene objema metodama razumno su usporedive sa stvarnim geofizičkim modelima. To sugerira da se bilo koja od metoda može koristiti za konstrukciju geološke sekcije. Međutim, rezultat eksperimenta randomiziranog cjelovitog projekta blokiranja (RCBD) pokazuje značajne razlike ovisno o korištenoj metodi, a to nameće potrebu za daljnjim ispitivanjima. Uparena usporedba sugerira da plus-minus metoda daje model koji bolje oponaša stvarne podatke u odnosu na konvencionalnu recipročnu metodu
